Different crank lengths on same bike?

I stripped the pedal threads on my non-drive side crank arm. I have a spare but it's 2.5mm shorter than the drive side. I have a long ride this weekend and won't be able to get a proper replacement till next week. Would riding with a 2.5mm difference feel weird or cause any problems? Ta

Depends if your legs are equal lengths.

I built up a beater from spare parts at work a few years ago and had 172.5 and 175, It was ok, noticed sometimes, when I was pushing hard. I wouldn't want to ride in anger.

That being said, if it's all you have then you're going to do the ride regardless!

Ah I see. Should be able to get a replacement soon enough. If however I was to ride on it for an extended period of time would it be likely to cause damage?

to you or the bike?

My knees mostly but perhaps the bottom bracket would be subject to undue stress too?

No, you and the bike will be fine. Toughen up and ride.

How longs the ride? There is no way I would do a long ride with two different length cranks 2.5mm doesn't sound a lot but at the end of 50 miles odd you'll notice. But it is doeable just depends on the person

Yeah, I wouldn't do it.

Having cleats in the wrong position can eff you up. Imagine having different length cranks!

Change to LHD at the half way point.

I think one of my legs is shorter than the other, amd this set-up sounds beneficial to me

Anyone with a long left leg wanna trade?

What about sticking 2.5 mm of washers between the cleat and the shoe on the 175mm side?

Would that work? Walking might feel a bit funny.

the washers surely would push the pedals outwards not upwards...

Huh?

Washers on the cleat on the shoe.

What I meant was if you unscrew the cleat, put the washers on the screws between the cleat and the shoe (assuming the screws are long enough), thus raising the shoe from the pedal by 2.5mm. This, hopefully, would approximate a crank that is 2.5mm shorter - maybe.

TBH, by the time we've argued this through, the OP will have got himself a new crank :-)

Your crank would be longer at the top and shorter at the bottom of your strokes if you do that...

Ah, I knew there a flaw in my reasoning. Thank you for spotting it. :-)

I disagree with the folk here, i really dont think you will notice. For all you know, one of your legs is slightly longer than the other and you end up doing yourself a favour. 2.5mm is nothing
